Knowledge
Students know:
- Linear relationships have input and output values that have an associated graph, including a y-intercept.
- parallel lines have the same slope but different y-intercepts.
Skills
Students are able to:
- Compare functions with the same slopes graphically while manipulating k values.
- Explore functions with a calculator or graphing software to develop a relationshipbetween the coefficient on x and the slope.
Understanding
Students understand that:
- Linear functions can shift based on factors other than the independent variable.
- The shift of a function is not the same as the stretch of a function.
Vocabulary
- Linear function
- Slope
- y-intercept
